WASHINGTON — Robert Bork says President Richard Nixon promised him the next Supreme Court vacancy after Bork complied with Nixon's order to fire Watergate special prosecutor Archibald Cox in 1973.

Bork's recollection of his role in the Saturday Night Massacre that culminated in Cox's firing is at the center of his slim memoir, "Saving Justice," that is being published posthumously by Encounter Books. Bork died in December at age 85.
